What is the purpose of a lockout/tagout procedure?

• A. To speed up maintenance.
• B. To prevent energy release or startup during maintenance.
• C. To document maintenance costs.
• D. To train new hires.

Answer: (C)

Lockout/tagout is about controlling hazardous energy to keep equipment from moving or energizing while maintenance is done. When a machine could energize or release stored energy, applying a lock to the energy source and tagging it provides a physical and visible barrier that prevents restarting the machine. This ensures the equipment stays in a safe, zero-energy state until a trained worker finishes the service and removes the devices. The aim is to protect workers from injuries or fatalities that could happen from unexpected startup or energy release. It isn’t about speeding up maintenance, documenting costs, or training new hires.
